DS90LV001TM - 800 Mbps 3.3V LVDS Buffer | Texas Instruments
Артикул: DS90LV001TM ✓ АктивенDS90LV001TM Обзор
An LVDS buffer is a low-voltage differential-signaling interface device that improves signal integrity by receiving a differential data stream and retransmitting it as a new LVDS signal. In the technology hierarchy, LVDS signaling belongs to high-speed differential interface electronics, while the DS90LV001TM is specifically a signal buffer rather than a general-purpose logic gate, transceiver, or isolation device. Its buffering function can isolate a transmitter from downstream loading and can help extend usable routing options when transmission-line impedances are controlled.
According to the Texas Instruments product page and manufacturer datasheet, key verified features include an 800 Mbps maximum data rate, 3.3 V supply operation, one buffered channel, CMOS technology, and an operating temperature range of -40 °C to +85 °C. The manufacturer describes the part as an LVDS-LVDS buffer, confirming that both the input and output use LVDS signaling. The distributor listings classify the DS90LV001TM as an 8-SOIC signal buffer or re-driver.
At the circuit level, the device provides a defined input stage, an internal signal path, and an LVDS output stage intended for controlled-impedance routing. LVDS systems commonly require correct termination, controlled differential impedance, and careful branch or stub management. Because the verified data identifies the part as an 800 Mbps LVDS buffer but does not provide detailed rise-time, jitter, propagation-delay, input-capacitance, output-voltage, or differential-threshold figures, those characteristics should be confirmed in the manufacturer datasheet before release to production.
Typical uses include LVDS clock distribution, point-to-point backplane links, cable extension, test and measurement equipment, industrial control systems, and communication equipment. In each case, the buffer is most useful when the source cannot reliably drive the complete downstream load or when regenerated edge behavior is preferable to continuing a lossy transmission-line segment.
The principal design task is preserving the intended LVDS signal integrity at 800 Mbps. Use a controlled-impedance PCB layer, place the device close to the relevant connector or receiver, apply the termination scheme specified by the system architecture, and avoid unnecessary stubs. Power and ground pins should have low-impedance bypass connections close to the device.
This page combines the verified Texas Instruments product information, distributor inventory references, package details, compatible orderable variants, and practical LVDS design guidance. It also distinguishes electrically equivalent catalog variants from true functional alternatives and identifies where detailed electrical, pricing, or lifecycle data still requires manufacturer confirmation.

Типичное применение
DS90LV001TM подходит для 6 применениеs: Industrial Backplane Signal Distribution, LVDS Clock Distribution, High-Speed Test and Measurement Link, Point-to-Point Data Cable Extension, Communication Equipment Interface Conditioning, Embedded Control and Instrumentation.
Industrial Backplane Signal Distribution
The DS90LV001TM fits point-to-point industrial backplane links that require an LVDS input to be regenerated as an LVDS output at rates up to 800 Mbps. Placing the buffer between a source and a downstream receiver can reduce the electrical loading seen by the original transmitter when the overall channel impedance and stub lengths are controlled. The verified 3.3 V supply and -40 °C to +85 °C operating range suit industrial temperature requirements, although the complete system still requires controlled-impedance routing, suitable termination, and EMC validation. The buffer does not add protocol framing or isolation; it preserves the differential signaling function while providing a regenerated edge at the output.

LVDS Clock Distribution
DS90LV001TM can be used to regenerate an LVDS clock before distributing it to another circuit, with a verified maximum signaling rate of 800 Mbps. The useful design question is whether the source clock, cable, and receiver require a new low-current edge rather than a passive splitter. Because the device is a 3.3 V single-channel LVDS buffer, it preserves differential signaling and can isolate the source from a controlled downstream load. Engineers should verify jitter, rise and fall time, and input and output thresholds in the Texas Instruments datasheet, while keeping branch lengths short and preserving the intended differential impedance.
Рекомендуется
High-Speed Test and Measurement Link
The DS90LV001TM is appropriate for test and measurement equipment that needs to route a high-speed differential clock or data stream over controlled PCB or cable interconnects. Its 800 Mbps capability provides margin for common low-speed digital interfaces, although a complete instrument may require higher rates or different voltage thresholds. The buffer can create a new LVDS output rather than simply continuing the original source into a long load. Designers should use short, impedance-controlled traces, follow the datasheet termination arrangement, and evaluate edge quality and jitter with appropriate test equipment before production release.
Рекомендуется
Point-to-Point Data Cable Extension
DS90LV001TM can sit near either end of a point-to-point cable link when an LVDS source or receiver cannot tolerate the total cable and termination load. The verified 3.3 V LVDS-to-LVDS architecture regenerates the signal rather than converting it to another logic family, making the device appropriate for compatible LVDS endpoints operating up to 800 Mbps. Cable length, connector geometry, dielectric loss, and common-mode behavior can dominate the result, so engineers should characterize the complete channel instead of assuming that the nominal data rate guarantees a particular cable distance. Proper LVDS termination and controlled board transitions remain essential.
Рекомендуется
Communication Equipment Interface Conditioning
The DS90LV001TM can provide a regenerated LVDS connection inside communication equipment where a transmitter drives a connector, backplane, or daughter card over a controlled differential channel. With an 800 Mbps rated rate, it is relevant to low- and medium-speed LVDS control, status, and data paths rather than high-speed serializer interfaces. The single-channel buffer allows a design to isolate one source from a downstream load without introducing an incompatible voltage family. Signal-integrity review should compare source and receiver thresholds, termination, trace length, and connector parasitics because the verified excerpts do not supply complete timing or voltage data.
Рекомендуется
Embedded Control and Instrumentation
DS90LV001TM is useful in embedded control and instrumentation assemblies that exchange high-speed differential signals between a controller and a remote measurement module. The -40 °C to +85 °C operating range covers many industrial environments, while the single LVDS input and LVDS output keep the interface electrically consistent with compatible equipment. The buffer can help isolate a controller pin from cable capacitance and provide a cleaner source for the next transmission-line segment. Layout remains critical: place the device near the connector or line-driver output, avoid long stubs, provide low-impedance supply bypassing, and verify the complete channel against the required edge rate and bit-error target.

Заметки по проектированию
Use a controlled-impedance PCB layer for the differential pair and minimize branch or stub lengths around the DS90LV001TM. The verified operating limit is 800 Mbps, so component and connector parasitics can materially affect edge quality. Follow the termination arrangement and input and output circuit shown in the Texas Instruments manufacturer datasheet, and verify eye quality, jitter, and differential voltage at the receiver rather than relying only on nominal data rate.
Place the DS90LV001TM near the connector, transmitter, or receiver it conditions, keeping the LVDS traces short between the device and the controlled-impedance transition. Route the differential pair over a continuous reference plane with symmetric geometry and avoid changing layer or width without a calculated impedance review. The SOIC package provides a compact surface-mount solution, but its lead inductance and board-routing discontinuities still matter at 800 Mbps.
Do not select the DS90LV001TM as a generic logic repeater or assume that any LVDS receiver is an electrically exact substitute. Verify differential input thresholds, output voltage, common-mode range, timing, supply current, fail-safe behavior, and termination requirements from the manufacturer datasheet. Also check the exact orderable suffix: DS90LV001TM, DS90LV001TMX, DS90LV001TM/NOPB, and DS90LV001TMX/NOPB can differ in packaging or lead-finish condition even when their core electrical ratings match.
Provide the DS90LV001TM with a stable 3.3 V supply and low-impedance decoupling connections at the device. The supplied verified data confirms the 3.3 V operating voltage but does not provide a complete power-consumption specification, so thermal and supply budgeting must use the current values in the official datasheet. Avoid placing noisy switching-current paths beneath or immediately beside the LVDS input and output traces, particularly when the link is used for precision measurement or low-jitter clock distribution.
Информация о соответствии
The supplied verified excerpts do not explicitly state RoHS, REACH, lead-free, halogen-free, or conflict-minerals status. AEC-Q100 is not applicable because DS90LV001TM is not identified as an automotive-qualified product. Compliance must be confirmed using the current manufacturer product page or declaration documentation.
